Im not really a Windows fan, and dont really trust it.. I use it for games otherwise im in linux or solaris.

I guess what I found nice with PING is that it will duplicate Everything including your windows and unix partitions and anything else on the drive.
So no hassels with a mutli OS boot disk.
Only Negative thing I can recall is that if you boot with both drives now being identical that XP 'not sure about the other versions' gets upset because of the two identical windows drive ID's.
but thats easy to solve.
